Abstract
An electromagnetic track brake for a railway vehicle comprises an elongate brake energizing coil for energizing a plurality of U-shaped braking shoes mounted in a row on a rigid frame. To improve transmission of braking reaction forces from the shoes to the vehicle each shoe is moved downwards individually relative to the frame against spring bias. A tie rod extends along a lower branch of the coil engaging each of the braking shoes for the transmission of braking forces from the shoes to the tie rod. A cylindrical rod rigidly coupled to the frame is operably connected to the end of the tie rod to take up the braking reaction forces transmitted to the tie rod.
